Tungsten Extract Service APIs
Tungsten Extract Service provides several RESTful APIs that perform OCR on submitted documents and tasks related to them.
For details on the APIs summarized below, see Tungsten Extract Service API Documentation.
Main APIs
Both of the main APIs take a document image as input and return JSON-formatted output containing the recognized text:
- performSync: Recommended for smaller documents where the caller can wait for the OCR to complete.
-
performAsync: Recommended for larger documents where OCR needs to be asynchronous. The API immediately returns an operation ID that can be used with the getResult API to retrieve the result once it is ready.
Other APIs
-
languages: This API retrieves a list of supported languages so the caller can build a user interface (if needed) where the language for OCR can be selected.
-
licenseVolume: This API returns the remaining license volumes and the expiry date of the licenses.
